Nokia has announced their very first speakerphone and the detachable Bluetooth unit makes talking in the car a breeze. The battery powered HF-300 boasts a speaker, microphone, 20 hours of talk time and Digital Signal Processing, which cancels out excessive clink and clatter while chatting in the car. It also knows when to turn off to conserve battery power as it shuts down after five minutes of downtime. The HF-300 will be available Q3 for about $122.
